Abstract

A novel method to eliminate additive drift in silicon thermal flow sensors, the Alternating Direction Method, is presented. In this sensor design the flow signal is contained in the gradient of a two-dimensional temperature distribution on the chip. This temperature gradient is induced by the convective heat transfer of the flowing medium, which is overall dependent on the physical aspects of the flowing medium, the physical characteristics of the sensor, and the thermal coupling of the sensor to its holder and environment.
